anyone know how i could correct those shadow things? mesh is 2048 lighting resolution. built on production
#aec-visualization

royal osprey
@hard oar Two things you can look at one is the texel density. And the other is something similar happened to a friend that had a really dark scene, it didn't look dark because post processing was using auto exposure to bring it up, he turned off "Game settings" for exposure, under View Mode and adjusted the intensity of his lights, after that the bake was fine.
hard oar
Thanks @royal osprey I will try it later!

Guys, I need your help to figure this thing out, I just did a little experiment to know how bad are "Ngons" and how UE4 will deal with them, so I did what I did in the video in the link below, and everything seems to be fine, I'm still a beginner, but I really want to know how bad are Ngons and when should I be aware of them.
I'm focusing mainly on Archviz, so not so much animation.

arctic mesa
@hard oar please report back of your findings; had somewhat a similar issue
in my case the baked AO gone horribly wrong
pale prairie
You shouldn't bake AO for archviz
arctic mesa
oh?
pale prairie
AO is to provide a rough approximation of shadow detail on objects when doing low quality/resolution light bakes or dynamic lighting that doesn't have GI
For archviz your lighting bakes should ideally be high enough quality that you don't need to simulate your gi
arctic mesa
hm.. that's actually quite fair; I never thought of it as such! thanks
pale prairie
Np, it's a mistake I always made until I read (if I remember correctly) an evermotion tutorial saying not to do it then I looked into what AO is and why not to do it etc...
arctic mesa
they used it in the apartment demo and they mention AO a couple times in the 'Understanding Global Illumination for Architectural Visualization' course. but yeahs; I see your point and it's a good one – after all I disabled AO bakes and my issues mostly went away
ripe crow
anyone know why my vertical lines are disappearing in the distance?
Im using megascan materials and displacement/normal maps.. ive tried turning off mipmaps
hard oar
@arctic mesa don't bake ao, anyway now i'm splitting walls into smaller meshes (one mesh was containing 3 walls cause the apartment is not that big). let's see how it's coming out
hard oar
@arctic mesa at the end i splitted everything and now workd perfectly
arctic mesa
that's useful to know; thanks!

Does anyone know how to fix m this? I'm trying to merge all the materials on this fireplace into an atlas but its coming out wrong. I want to reduce drawcalls in my scene and I need to do this to static meshes that have been combined into one static mesh, like this fireplace. looks either like extreme pixelation or no normals/roughness etc. Settings are on the right. I cant figure it out.

after all this mess with the lights; I just grabbed the DSLR; went and took a bunch of ref photos and then set the UE's camera settings to match and boom – the scene looks almost as expected with the crazy ramped up sun (125000 lux) and skylight (4500 cd/m²)

Hi, I would like to ask how do u solve contact shadows on furnitures?
left side is Vray - right side is unreal
This scene is from Archinteriors 54. The unreal version is lit with HDRI backdrop and stationary directional light.
And some rectangular light on the windows to fill the space with GI
I can't seem to get the dark shadow on under the sofa and at the legs of the chair.
sweet fossil
Very high lightmap resolution + GPU Lightmass
fallow grove
@sweet fossil the wood floor has a red color already on the lightmap density view. it's at 512 right now. and i am already using the GPU light mass setting which I copied from one of the guys who are getting realistic results,which is NumPrimaryGISamples=128NumSecondaryGISamples=128FireflyClampingThreshold=10000.0. On the previous view, the lack of contact shadows can be seen, but on this other view, it is not that noticeable. Should I Increase light map resolution to 1024? thanks in advance!
solemn hawk
For large surfaces like floors and walls i usually use 1024 or 2048 depending on how the end result looks
sweet fossil
Agreed, go wild on floors
fallow grove
Thanks, I went wild to 2048, and it’s almost the same, no dark shadows on the contact between the sofa and the floor. i tried using 0.1 on the contact shadow setting on the directional light, but it ads a thick dark shadow which isn’t realistic. I also tried changing the material of the floor, the same result. Or maybe change the lighting technique? Lol
Is this normal?
pale prairie
I'm not sure why, but there seems to be a strange lack of occlusion in your scene.
Can you share your lightmass settings and go a little more in detail on your lighting setup
Also for realism it's generally safer to go with a physically accurate lighting setup (like 1 sun and 1 skylight) and take advantage of lightmass portals and such
The use of lighting tricks like bounce cards, spotlights and rect lights to simulate gi can have wonky effects
Also Unreal engine is pretty bad when it comes to using HDRI's for lighting at least when compared to traditional offline renderers so you need some tweaking and workarounds to get good results usually
fallow grove
@pale prairie I'm just mixing up tutorials that I found so feel free to guide or correct me.
Reflections, I turned on Raytracing for Reflections
1 Directional Light
1 HDRI backdrop
4 LightmassPortal on each window
4 rectangular Light
Thanks to you all!
solemn hawk
Can you post a screenshot of the “lighting only” view?
fallow grove
Hi, just an update, i solved it by erasing all the lights, post processing volume and hdri backdrop. Then I relight it with the traditional directional light, skylight with specified cubemap(HDRI) and a skysphere as background. Then did 2 lighting scenario. A day and night scene. I still dont know what caused it. If you can comment on my work for further improvement, i will be so thankful. Thanks!

Hi, is there a way to smoothen the change of lighting scenario? I have done it through blueprint based on youtube tutorials but the transition is not smooth.

@fallow grove there’s not,
What I would do is have a loading screen pop up and do a fade animation, they can be fun to get creative with.
then have the loading screen disappear when the level is fully loaded

Can anyone help me solve this lighting problem? I have a large photogrammetry landscape but for some reason there is a small piece of my level that doesn't receive light correctly.

hey, could you please remind me, does old gpu lightbaker support baking indirect light from non-skylight light source (point light source in my case)? If i'm using such source as the only one in empty scene with few meshes, I can see only baked direct light, everything else is black. I thought light would bounce around a bit? It's been a while since I was poking in ue4 so I'm not sure if it's my mistake, or just good ole limitation

This is not really related to Arc-Viz but more about Product Photography... I am trying to add HDRI maps to an Rect Light. But for some reason once I do that the light stops working. Any thoughts on this topic?
ocean ledge
@hexed knoll You could probably achieve that by using the HDRI in a Light Function material. But I actually never tried that, so it's more like a shot in the blue.
hexed knoll
@ocean ledge Thank you, This pipeline is very organic in VFX and CG product photography. We basically take HDRI of lights and use the to light products or shots in order recreate the on-set setup or a physical product shoot.
@ocean ledge Here is an example on how i will like to use them in UE4 https://vimeo.com/206200206
ocean ledge
It's like image based lighting but instead of a dome on individual lights?
@hexed knoll
hexed knoll
@ocean ledge That is correct, it adds the complexity and quality of real world lights/lighting. Specially if one was to consider, everything we see in film and TV is filmed using On SET lights.
CG lights are too flat. Nothing in real world emits light like the RECT light. It's probably the equivalent of adding Roughness to a material.
ember notch
has anyone ever had these lightmap seams from several wall pieces sticked together?
i have clean uv1 and uv2 channels and 512 lightmap res for each piece
royal osprey
@ember notch it is a know limitation, you should have one wall.
ember notch
one big wall?
@royal osprey
it will have one huge lightmap which will need a huge resolution which will crush performance
just had to lower the lighting scale to 0.1 and the seams vanished
ember notch
@royal osprey i noticed that you need to delete the inner faces of the walls that are overlapping coz the lightmap will render them black and that will bleed to the outside
royal osprey
Unreal only casts shadows if the normal is facing towards the light source so if you have walls with no geometry outside the sun will come in, but if you have a table with no bottom face it will cast a shadow, ( Some 3 software is the other way around, oddly enough) You should, use "shadow 2 sided" to mitigate this but even so you could still end up with light leaks. a solution often used is walls with thickness, but it's wasted space in the lightmap if you have stuff that is large in the lightmap that will not be seen. so what I do is to make my walls with no thickness and make an extra box facing outwards with the windows cut out and with low lightmass resolution to cover the outside.

I'm following the Chris Murphy Udemy tutorial, every step of the way, yet my scene looks different, especially this. I have soft shadows on the brickwall, but all my white walls have this weird thing. In the course it's soft as well. How do I fix this?
Some side questions:
- My sun is completely elsewhere then the direction from which it's shining, not sure why this is?
- I changed the light units from candela to lumens, yet I still need to put a candela value in my spotlights, why is this?

alright, thanks, I think I might install 4.22 to check out
lucid orbit
I think I might have figured out what's the issue - checking off inverse falloff breaks indirect lightning 😦 This issue doesn't affect the CPU baker, just the luoshuang's GPU baker
after enabling it back and putting in a gargantuan number in intensity (I use Spot light for lightning large room, around 150x150 meters), I got to see bounced light

@weary trellis if you can, I'd avoid using a laptop but that one will work.
Hey @ripe tartan nice work. First thing that pops out to me as a bit off is the couch looks pretty solid and not soft, also the stonework behind the shelving looks like it's weirdly lit.
Second image is solid
royal garnet
1 - Seems a bit weird.. Not sure where this shadow originates, but given the current framing I would expect the shadow to fall differently.
2 - Can't really make out whether it should be glass or plastic. This Object and the surrounding region seem to be missing reflections (Just my opinion)
3- highlight from outside? Looks like an artifact in this image.
4- Are they supposed to be movable? if yes, they are missing some rails. If no, it feels like weird choice to have multiple panels overlap like they do. And they seem really fragile because only one Panel connects to the wall and none connects to the ceiling.
A few things do look a bit too clean/boxy (carpet) even for archviz, but overall it's already quite good in my opinion.

thanks for the feedback @royal garnet
this was the last of 3 apartments i had to moddel, at first i was paying attention to these details but after so much modelling i lost the eye for it
royal garnet
You should look into Datasmith: https://docs.unrealengine.com/en-US/Engine/Content/Importing/Datasmith/SoftwareInteropGuides/IFC/index.html Haven't used it for ifc, so not sure whether you can modify the import settings to generate lower resolution Meshes.
If Datasmith doesn't work, you could try and use the automesh reduction feature and then force a lower LOD Level.. That's quite a hacky way though. Using a 3D app to do a automatic reduction and retopo might be faster and surely more accurate. Today's auto retopo and reduction tools are quite good.. So it's worth a try.
crimson zinc
Can anyone give me an insight on why light is glitching? This is just one of the problems I'm running against whilst using VRscene (VRay) exporter
is this due to tris count? (i'm trying not to use foliage)
vernal pecan
@ripe tartan I would also suggest using Dataprep on top of Datasmith to build yourself a nice workflow for optimizing your imports https://docs.unrealengine.com/en-US/Engine/Content/Importing/Dataprep/index.html
Dataprep allows you to use the LOD and HLOD tools of the engine at import, aswell material setup, geometry merging, lightmap density optimisation... and much more
median rivet
@hallow arrow or if anyone else can chime in. I recall having a conversation with him regarding HDRI lighting and using GPULightmass. And he mentioned that the HDRI cubemaps are actually downsampled from original size. Does anyone know if this is still the case? I havent done any recent testing with the latest version of Unreal.
dusty gyro
@forest depot hey there ! I cant remember, are you using Datasmith to import your scenes in UE ?
forest depot
Hey, no we don't
forest depot
I guess we know exactly how many meshes we will end up having, what will be assigned to each mesh before modelling. We aren't an architectural company, so we intererpret designs by architects and build them from scratch.
We don't see a way around rebuilding architects models from scratch
dusty gyro
Are you guys using 3dsMax to model the scenes ?
And is there some preparation steps done manually* in UE like LODs, lightmaps, stuff like that
forest depot
Yeah we use max to model the scenes
We uv lightmaps before going to unreal by hand
We also do LoDs by eye and do a lot of testing back and forth as we find automation to be too inaccurate
dusty gyro
ah alright
forest depot
I'm keen to see if we can improve our workflow with it though, if there's any good examples you think might be helpful
dusty gyro
Well you could at least use Datasmith to transfer the scenes from Max to Unreal, instead of FBX. Starting from here you will have access to a robust reimport workflow
And they if you want to add automation for whatever task you are currently doing by hand in Unreal, like lods or lightmaps, you can go through Dataprep aswell
vernal pecan
@forest depot I'd be interested to talk about your workflow and how Datasmith and Dataprep could help your team, we can PM if you want to discuss about it

Hi guys,
so am I fairly new to ArchViz in Unreal and I‘ve watched already quite a few videos about ArchViz lighting. Now I want to know, how I should model, for example a room in the 3D software. Should I model the whole room in one piece or split the room in separate pieces, like walls, ceiling and roof? Thank you guys in advance
royal osprey
split it up, but try not to leave seams on flat areas
like two floor pieces or two wall pieces on the same plane should be one piece
the more you split it up the more control you'll have on lightmap resolution. Also if you have furniture that repeats only make one, it makes future adjustments and changes easier.
little star
Thanks @royal osprey, what do you mean with not to leave seams on flat areas?
royal osprey
it is a common mistake to split a large wall into two, it can produce visible differences on lightmaps
arctic mesa
speaking of – some demos only use planes for the walls and a big wrapping cube (so that the light won't leak), others use cubes. Any actual pros and cons to those? I understand that having the faces you never going to see impacts the lightmap resolution but if you do manual lightmap UVs you can make the invisible faces occupy a tiny UV space
royal osprey
I tend to make what I call a "black box" around interior shots, only windows showing.
and sometimes add extra boxes in Unreal if I missed a piece.
little star
To prevent leaking you can just add depth in the modeling software, right?
royal osprey
Unreal casts shadows away from the normals, so you need walls facing outwards too.
yes
you can add thickness to your walls, the advantage of using a separate object is that you can control the ligtmap resolution of the outside independently (make it really low to save time and resources)
for games it is common to delete polygons that the camera will not see, but for Archviz it's better to leave them (like the bottom part of a table) the lighting will be more accurate that way.
little star
I had a problem with a room I build, one piece, just separate floor and ceiling. As I built the light, it started leaking on the edges of the floor and ceiling and I don‘t know why
royal osprey
I've had some really stubborn leaks too. sometimes Unreal borks the bake and only thing that fixes it is to delete the level's .builddata file
arctic mesa
I actually had pretty good success with raytracing GI as a means to fix my light bleeding. I'm not sure if that's an acceptable solution for the commercial archviz use but I got my nice screenshots out of it which was what I wanted
royal osprey
Some leaks are not really lighting but glossy or specular reflections.
little star
How to get rid of them?
royal osprey
if they come from reflections you need to tweak your reflection probes, materials or specular size of the lights
@arctic mesa yeah it usually works. I've done dozens of scenes and only a couple have given me problems.
Another common mistake is leaving auto exposure on when you start lighting the scene.
arctic mesa

@arctic mesa so how can I find the Raytracing GI option? Do you have a link to that or a tutorial?

@little star follow the 'enabling raytracing' in here: https://docs.unrealengine.com/en-US/Engine/Rendering/RayTracing/index.html
but it only works on some videocards

no problem at all. It's not like it's a silver bullet, but it makes some issues much easier to tackle

mint igloo
Guys, please a little help here. I have created a loading screen but after the loadingscreen, it doesn't load my level even though I have set it to open level which is the walkthrough. Did I do something wrong?
royal garnet
@mint igloo Check Log for possible Errors, set break points to check the state of your game at the moment it should load the level (Does it ever reach this node?). Did you load it async / sync? Are you using seamsless travel or not.. etc. There's quite a few ways to achieve a loadingscreen, so we would need to know more (what walkthrough?). Here's a yt video that shows loadingscreens (unreal fest 19) https://www.youtube.com/watch?v=ON1_dEHoNDg

My guess is a lightmap uv problem. But you might be able to solve it by increasing the lightmass resolution on those pieces.

Can someone help me with ray tracing interior arch viz scenes without noise.
I get so much noise whenever I move my camera. I have increased sample count in gi to 64
forest depot
If that's RTGI, thats just how noisy it is
If you don't want noise you need to bake
opal maple
Ok how to take screenshots or render using this
Baking takes so much time to achieve this same quality
forest depot
You can see in the official ue4 rtgi archviz example scene made by Pasquale scionti is exactly that noisy
Yep, and 99% of us bake
opal maple
Then what is the point of ray tracing?
Then why UE4.25 says ray tracing is production ready
forest depot
🙃
opal maple
How games like control using all rt features doesn't have noise?
Is it with unreal or rtx tech itself is limited
forest depot
They do have noise
Very few games use RTGI
But games rarely have clean white walls
You can't notice it in something like metro ... The only game that comes to mind with RTGI
But yeah raytraced shadows and reflections are amazing and work much better than rtgi
opal maple
CONTROL has all features
And it doesn't have that much noise
Like no noise when moving camera so fast during intense gameplay
But in UE4 static archviz scenes without much movement produces so much noise
U can check CONTROL gameplay
forest depot
I'm pretty sure control only has 1 bounce so they can crank the samples
autumn ember
hi guys
my model comes with a uv2 created in 3d software for lightmap specically
can i use these uv2 channels in UE instead of having it to re-generate its own lightmap uv ?
basically i want UE to bake the lightmap using the premade uv2
sweet fossil
yes just disable "Generate lightmap UVs" on import or if youve already done it, just set you lightmap coordinate index correctly
autumn ember
Just some of my WIP using UE 4.25 RT. Any critics/suggestion would be nice.

I was wondering if anyone had any guidance on how to do a rooftop garden. I would like to do it with the same kind of functionality as a landscape material that procedurally generates specific foliage meshes in painted areas. I know I can paint with the foliage tool, but it seems a little more cumbersome, I want to easily be able to paint in the other foliage type, not to mention the texture change on the actual material to make certain types of plants blend and look more realistic. I tried googling if landscape materials can be used on static mesh and I’m getting a no for that. So I’m asking if anyone has any ideas or have done something that worked well in the past. There are different levels and terraces for these rooftop garden areas throughout the building. Thank you for the help in advance.
sweet fossil
how to get rid of this kind of artifacts? UV is fine but it happens with almost every mesh im importing.
@fair forge In the import settings dialog, make sure to set "use full precision UVs" to get rid of this.

@sweet fossil there are no such checkbox here

Just use layers?
You could adjust the near clipping plane dynamically I guess but it wouldn't work in all circumstances

I have never had this problem before and wasn't able to find a solution online. Does anyone know what can cause this and how to fix it?
Im on cpu
forest depot
check your swarm cache, might need clearing
worst case, reinstall that particular version of unreal
pastel summit
clearing didnt work.. guess i have to reinstall then.
its just telling me its time to switch to gpu haha
forest depot
well its true 🙂
pastel summit
haha
pastel summit
@forest depot reinstalled the whole engine, still didnt work
forest depot
oh dear
pastel summit
yup
forest depot
should probably try gpu lm : D
forest depot
its good practice 😉
pastel summit
true
does it look as good as standard cpu or does there need to be done some tweaking to get good bake results
forest depot
doesnt take much
pastel summit
its only unitl 4.22?
pastel summit
guess i will try 4.22 then, so i can use you as a main source for troubleshooting :p
pastel summit
prepare to wake up to spam :p
ripe tartan
@pastel summit found this "solution" online
This is what fixed it for me. More specifically, I used the following steps:
Delete the first 20% of assets
Try and start a build.
If Swarm doesn't kick off, delete another 20% of assets.
If Swarm successfully starts, then cancel and shut down UE4 without saving anything.
re-open the project, and build. Swarm should work.
pastel summit
Tried that to didnt work for me. It worked but when i rebuild it without saving same error but thanks
I fixed it btw it was a problem with a specific file name that om read caused an error
Changing the name fixed it

hello, ive been having this same problem every time I bake the lighting - a large patch of light radiating from the centre of the cupboards. the only light sources i have are
the window on the left, as well as a strip of light on the top and bottom of the upper cabinets. anyone know what might be causing this?

Indirect light leaks- Whats the easiest way to get rid of these?
my volumetric lightmap inside is fine, but its interpolating to samples outside

@hidden crow have you been trying out the different sampling methods ?

Oh, do you just mean the 3 parameters for sampling control?

Yeah on your mesh components
I don't have a computer at hand and can't find the exact name of that setting, but it's in the mesh component lighting settings I think ?
ripe tartan
do you guys use volumetric fog in your archviz projects?

royal osprey
@ripe tartan Fog is usually not desirable in arch viz, but I have used it for nightclub to simulate the light cones.
ripe tartan
tnx @royal osprey
median rivet
Any ideas as to what might be causing this? The image showing far away from the cabinets, the material looks completely black, whereas if i move close, you can start seeing the actual material intensity, there seems to be some strange circular effect around where i'm close to the mesh the material shows fine, however at distant it shows black.
Another angle...i dont have any sort of falloff in the material, basic diffuse/roughness/normal ... never experienced this before
sweet fossil
Have you put any reflection captures in your scene?
median rivet
@sweet fossil Thanks for the suggestion. I did have reflection captures, that was my first guess as well. Turns out, the DDS files that I was downloading was somehow corrupt, recreating the DDS file and repulling fixed the issue. No explanation, but it now works lol

hallow arrow
yep, you still need devR, which is hyper unstable these days 😞
forest depot
Yeah I can't really use devrendering except for tests
Anything new except for denoising? @hallow arrow
I know you said it would be roughly 10x slower
It's supposed to sample full res from materials now?
hallow arrow
advanced GI algorithms, like irradiacne caching * ray guiding
without denoiser now it is 4x slower than the old one
with denoiser, 🤔 it could actually be faster
forest depot
Oh wow ok
hallow arrow
It's supposed to sample full res from materials now?
yes
forest depot
I also just got a rtx 8000, would the new gpulm benefit from the cuda cores?
It also works with swarm natively right?
hallow arrow
yes, as materials are evaluated on cuda cores
no, currently no swarm support, but multigpu support
hallow arrow
vlm has all support, except denoising
no good way to denoise a volume texture currently

@ripe tartan you want to use correct mulptipliers for you static lighting level scale and inderect lighting quality to reduce the most artifacts
so for 0.1 use a quality 0f 10 for 0.2 one of 5 and 0.5 a quality of 2

More indirect lighting leak stuff. I posted this on level design subforum here but maybe arch vis people have ideas:
I have been fixing indirect light leaks in my level- mostly resolved except this one through the ceiling. Suggestions? Notice the indirect lighting getting interpolated through the ceiling.
I fixed the leaks from the back wall by increasing the size of the indirect lighting volume and making a double wall so the sampl its blending to isn't in full sun. Can't make the ceiling any thicker without screwing up window placement

is it ok for unreal to make a whole condominium exterior, archviz project?

Hello guys. I hope this section is an appropriate place where I can ask a question. Can I do quality Archviz, interior renderers with the following configuration. AMD Ryzen 7 1700 8core 3GHz / GTX1060 6g ram 24GB. Is an RTX graphics card necessary or? The projects are mostly 10/12 GB size. Tnx!

yeah thats not a problem at all
we almost run the same configuration only difrence is that i run an intel on my machine never had any problems
pliant basalt
I would like to try the engine, but I read somewhere that this model of graphics card renders very slowly. That an RTX series is needed because of ray tracing. That's why I asked, I won't install it for nothing as I don't have the appropriate hardware. Thank you for your help.

i dont have an rtx you should be fine. baked lighting is the way to go for better quallity. its ussualy used for the reflections. but ssr goes a far way

Looking for some guidance here. I’m working on a large arch viz scene with a couple of blocks of buildings. When I add foliage to the scene is gets pretty sluggish. Using the foliage tool and HLOD -aggressively. Flipping to billboards fast. Which is fine for now since I’m still set dressing and these will be still renders. But my question is, should I put foliage in a different level streamed in? I’ve had issues with foliage in my main level not being able to be deleted when painted on (just like one or two bushes that would only delete with the delete all function) So I’m also looking to avoid this problem if I can.

hey guys, i've been thinking... when you guys accept a archviz project, do you ask for the interior project from the client or you do the interior?
royal osprey
If I'm doing an interior I always get floorplan and a material /furniture reference library. An sometimes a mood board. If that is what you were asking.
floral geyser
Thanks for the input @void halo
@ripe tartan depends if contracted for interior renderings as part of the deliverables. If not contracted for interiors, areas that get seen in exterior stuff usually just roughed in based of floorplan and styled from moodboard client likes. If contracted for interiors, try to get as much info as possible. Let them know we can include specific furniture/ hardware/finishes if they have it selected, but it’s more cost effective for us to use something similar to the look from our existing library.

@forest depot me.. y?
I had a weird experience, all is fine and building test lights, but when i start to add more static mesh by datasmith, i reached the point that my 11gb gpu memory is not enough for building light, i force delete, some assets and tried rendering again, what happened is it will start to build light then suddenly stops without any warning. But when i test it on a new empty scene, it’s all fine. And when i revert back to cpu lightmass, the, problematic file builds successfully.
So just for that project, i build the lights with cpu lightmass. And for other new projects, gpu lightmass on 4.25 is doing fine for me.

@broken radish When I was a freelancer I would never charge per render or per minute of finished animation. Projects tended to vary wildly so it was not a fair way to charge. What I did was to break down the work into individual tasks and estimate how many hours total it would take, then multiply the number of hours by my hourly rate, then I would double that to cover hardware/software/rent.
broken radish
that makes more sence
coz I did like 40 hour
I estimate like 20€/h
but I think it might be low
Unless i double it to cover expenses like you said

20 per hour not really that low in todays market, considering people can outsource to india, china or south america for some surprisingly good 3d assets.

Hi, i have a few questions about laptop specs needed for arch viz? is rtx or gtx better? 8GB Ram is enough?
valid mantle
RTX is a lot better, and 8GB is enough but more is always better
weary trellis
Right, so is it better to to spend an extra 500 dollars for better RAM? (i'll potentially be using the laptop for a while)
I'm looking at MSI model laptops btw
valid mantle
if your looking for a laptop probably somewhere around rtx 2070 would be best choice, and same with desktop
if your looking for budget 2060 is enough to start
weary trellis
Yeah its rtx 2060
valid mantle
yeah 2060 would be enough to start but also you may want to wait for a bit
new cards will be announced soon, for the RTX 3000series
so cards may be getting cheaper in the near future
valid mantle
cards should be out by october but not 100% sure
valid mantle
yeah no problem
ryzen 7 would be a great start
32GB would be optimal but 16 is enough Ram
weary trellis
right
valid mantle
if its a laptop then you don't really have to worry just find one with 16GB ram
if your getting a desktop Ryzen CPUs prefer hiigher mhz in ram
roughly 2666+ for Ram mhz
weary trellis
Ah I'll need to keep that in mind when i start building one in the future, right now I'll need to settle for a laptop, since my current one can't handle anything for schoolwork
valid mantle
hahah, yeah fair enough thats pretty good starting though so you should be fine
floral geyser
@weary trellis I recently got an MSI GE raider laptop to work in unreal rtx on the go. As a side note about (msi laptops) rtx will crash unless the laptop is plugged into an external monitor and screen 1 laptop monitor is disabled. It switches to the integrated GPU no matter what settings are specified by nvidia or the msi software otherwise causing a crash. Not great for portable but runs just great with an external monitor. I’ve read in the forums that other laptop brands allow you to disable integrated graphics from bios. Cheers!

i thought it will be just like the old version with enabling geometry but this is a bit different
also do you know how can i spawn a box brush so i can edit it
austere hazel
How do you guys deliver your projects?
- render only stills/videos - what's the point of using ue4 with vray around (arguable)
- bring your powerful pc to the client - he only sees it when you're around
- tell them they need a powerful pc - not everyone will be able to see it
- stream it with Amazon App streaming - it costs money if a lot of people watch your project a lot
reef dock
any pointers some one can give me im using 3ds max and when ever i try to combine 2 walls next to each other i get this line in between them
reef dock
like creating 2 walls and level them to site next to each other like so in the pic those are 2 walls
forest depot
@austere hazel tell them they need a powerful PC
obviously you still deliver the stills and videos
sweet fossil
yeah I can tell, what's your experience with 3D modelling?
reef dock
from scale 1-10 is 2-3
sweet fossil
you can't really measure experience on a 1-10 scale - no matter how those "50 free resume template" articles tell you
sweet fossil
Basically the first image looks fine, you're only seeing a line due to aliasing, however you shouldn't really have interior geometry like that
reef dock
this is for an exterior wall
sweet fossil
I mean you have two faces sitting right on top of eachother
forest depot
I think I see the issue
you shouldnt 'push up' two walls together
you need to learn fundamentals of 3d modelling
and it should be a single object
reef dock
even in ue its like that
forest depot
I just described why
sweet fossil
and it should be a single object
@forest depot not necessarily but yes these problems essentially come down to lack of fundamental knowledge
reef dock
i see it should be an l shaped ?
sweet fossil
it should only need to be 2 faces there
reef dock
in a simpler way 🙂
reef dock
thats what im trying to do how can i go about doing that
sweet fossil
it should really only be this
forest depot
well yeah depends if they are going inside teh building or not
sweet fossil
you don't want to have interior and exterior walls part of the same mesh
forest depot
thats a pretty advanced concept @sweet fossil if they dontt know modelling fundamentals
reef dock
so @sweet fossil is that a 2 face wall in the pic ?
sweet fossil
Best to get it out the way before they come back asking more questions related to why lightmaps look weird
Yes, only 2 faces
ArchViz in UE4 is a fine balancing act. You need to have as much texel density in your lightmaps without having to crank it to 4096 per mesh
reef dock
ok so i dont need to do the width just use that for my exterior and when i starting doing my interior it will be another wall from the inside correct
sweet fossil
yes
If it's easier you can model it all as one solid piece, just remember to seperate out into smaller pieces at the end
forest depot
yes thats right... however you will need to learn a lot of basic 3d modelling to really get much out of this
reef dock
well u see i tried doing it in ue but i faced some problem since i dont know how to add a door into a wall like im able in the 4.23 version
sweet fossil
oh yikes don't use BSP
reef dock
thats why i turned to 3ds i know its way harder but i thought i will give it a shoot
had it for a year and never used it
forest depot
you should be doing it in 3ds max or any 3d software
its just you need to find some basic tutorials to get the hang of things
reef dock
i have watched some in the past but forgot most of them
any recommendation on good tut for 3ds that explain stuff really good and not just rush it
well i appreciate your guys help
sweet fossil
Sorry I don't know any decent tutorials. I recommend checking the Unreal Online Learning portal though

hey, I've tested Twinmotion for first time yesterday, it was curious tool, but I'm a bit out of loop when it comes to its licensing, could someone fill my knowledge holes? It was at first a separate app for quick archviz/landscape projects, with graphic engine based on ue4, then epic bought it and it made it free to anyone who added it to library at some period of 2019 (which I did), free until december 2021. Does it apply to all versions of Twinmotion? (in epic launcher, there were 3 versions, 2019, 2020 and 2019 epic version, so it confuses me there). Once december 2021 passes, none of Twinmotion versions will be free anymore and it will be a product that epic is going to sell simply as commercial product. Did I miss anything?
Family is preparing to build a house and I'm debating whether I should stick to ue4 for full control/future-proof, or invest learning twinmotion and use it for quick visualization/iterations (but if it becomes eventually a 1.5k+ $ software, it makes me debating myself)
royal osprey
Well it's $500 USD for the perpetual licence now and the bridge to unreal is being worked on. https://portal.productboard.com/7pu88c9kpmqtzt8hwg6arujh/c/83-import-twinmotion-projects-in-unreal-engine

@azure vigil "Saved\Config\Windows\EditorPerProjectUserSettings.ini" search for "RendererSettings.RayTracing" and set to false
Also it's probably locking up on load due to compiling shaders.
azure vigil
Ok thanks! The problem is that it starts loading then shuts off automatically

@sweet fossil it has something to do with glass materials, somehow raytracing can't see through them

Hi all, does anyone know how to get an e57 into UE4? I've seen that it's in the pipeline to be supported, but isn't at this stage. I'm still having to use 4.24 to import PTS using the Lidar plugin, which is a solution but definitely not optimal. I saw that it was added natively with 4.25, but I cannot find anything in the documentation or online in general about how to actually import files. Simply importing via CB doesn't work; it doesn't see the files. So I'm stuck with 4.24 for the time being, but any solution involving 4.25 and/or e57 would be HUGELY, HUGELY appreciated 😊

Hi all, I just created a new epic store account for our firm, but when I try to install Twinmotion it only allows me to install it as a Trial. On my old account I can install the full version (2020.1) but I haven't payed anything. How come I got it for free on my old account? And for how long its going to stay free?
From my personal account. (On the firm's I can only select 2020.1 Trial)
gritty bloom
What if I already registered for Epic’s free 2019 version of Twinmotion?
You may continue to use the free 2019 version if you desire, however as a thank-you for your early interest in Twinmotion, Epic is pleased to offer you a free upgrade to Twinmotion 2020.1 and all subsequent releases until December 31, 2021. This entitlement is automatically added to your account, and you can access the new releases directly from the Epic Games launcher.

How do I get rid of those hard light/shadow changes? I have an hdri outside + a soft directional light
ripe tartan
how do you guys charge for your work? 👀
royal osprey
@ripe tartan You can get a ballpark number if you break down the work into individual tasks and estimate how many hours total it would take, then multiply the number of hours by hourly rate, then double that to cover hardware/software/rent. If the client is high profile or very demanding you can go over that, but that's the general idea. I try to stay away from simplified charging methods (by image or second of animation) since projects vary so much.
ripe tartan
thankyou very much @royal osprey, that was very clarifying
we were charging by m2, but i don't feel very confident about that because, that's what you said, not every job has the same complexity

Guys i want to make a video on the sequencer with lights turning on and off also a few objects moving... How do i do it without losing the baked light from the objects? T_T
sweet fossil
Your only option for turning lights on and off is lighting scenarios. As for moving objects you'd have to make them movable and not use static lighting on them.
well you could keep the static shows on the object you want to move by forcing the lighting type to static but you'd need to make sure it doesn't cast static shadows or it will leave the shadow in place after it moves

@sweet fossil i changed to full ray tracing environment. Now when i record a sequence, i get black splotches from rtx global ilumination... Need to find how to dodge that...
@sweet fossil thanks for the reply by the way 👍
forest depot
You kinda have to change the way you light to accommodate full rtgi, there's a lot more cheating with fill lights to get rid of the noise
boreal meadow
@forest depot Thanks for the reply man. I gave up last night, for this project i'm using only rtx reflections and maybe occlusion. I don't mind the noise on the viewport, what bothers me is that even when i render a video with sequencer the noise is recorded too... Doesn't make sens to me as when it is rendering a video it is going frame by frame it should take the time it needs to render wihtout the noise...

@forest depot well im curious. I tried to do this trick with fill lights... it worked but i couldn't manage to do it properly...

Hi Folks:
I have a project that I am working on right now that I would like some ideas on how to proceed. I am building a model of a travel trailer. I’d like to be able to walk through it in a nice setting (First Person Shooter style, but without a gun) Id like to be able to activate buttons to slide out the sliders, have the lights and ceiling fans turn on, raise and lower bunks etc. Ive never really done something like this – Ive looked at Unreal, and I also have the demo of TwinMotion (This is a personal learning project, so no TOS violations there). Id also really like this to not be stupid hard, or if it is to have a good set of instructions. What can you recommend?
Thanks

@mellow crater I'd start with what's available on Unreal Online Learning

@solemn ether The Normal Camera is usually for in-game stuff, like a third person camera. Cine Camera is for all cinematic stuff, like rendering walkthroughs or creating cutscenes where you want it to behave more like a real world camera. For a video walkthrough I would definitely use a Cine camera!

I am 100% a newbie at unreal. BUT i found a workaround for me on reflections beeing brighter than the actual scene: here the color of my mirror is set to full white, making the reflections brighter than the scene...
but when i play with the color, i can adjust the mirror to match the actual scene brightness!
and i can play with it until i get a perfect match

It should actually be a little bit darker, mirrors are not 100% reflective. Some of them give out a green tint.

Hey all, has anyone had any experience using composure with the new movie render queue? I'm looking to output some high res image sequences that the new high res movie queue output will be perfect. I'm just not sure how I might go about rendering the individual AOV passes from composure in the render queue. Does anyone have any experience with this?
zinc shale
Hi, I was trying to get into composure to generate a sequence with transparent background. But I completely failed to follow any tutorial and I'm either too stupid or the thing is unnecessarily complicated
queen kiln
@zinc shale Hmmm interesting. Well I've had composure working with the usual render output from level sequencer. If you're looking to output an alpha pass, did you set up layers for foreground/background actors?
There may be a better practice for this but my understanding is that you assign you actors to layers and then add them as an actor set to include or exclude in the comp (lazy example in image).
In terms of composure with render queue manager, I did a little more reading. Looks like queue manager doesn't support composure yet. 🤷♂️
zinc shale
Yeah I had it set up like that, but it wasn't saving any output when I set sequencer to output composure passes and I also think it wouldn't even allow to set png as output. Nevermind, gonna try again, thanks.
ripe tartan
lol, i was having a problem with ray-tracing reflective objects not seeing refractive surfaces as translucent at reflections, and now, 1 month later i realized that you cant have a refractive tex and a non refractive texture in the same object, the raytrace won't see it as refractive, you need to separate the refractive surface from the object to work
now it's working fine
these bugs will kill me one day

Hi all, does anyone have any experience with sequence recorder? I have a first person character that is being recorded, which has a spring arm with a camera as its child. For some reason the sequence recorder is not recording the up and down rotation of the camera, only the left and right is. It seems the springarm is not meant to go up and down, yet when I press play it works, but with the recorder it isnt? Is there a way to record the camera without the springarm?
the springarm is necessary due to camera lag and camera rotation lag to smoothen it out

I have doubt that it is possible to make a feature like , In a multiplayer game one person should be able to tag along with another person (Example :- A tour guide shows the places to the tourist) Not like the tourist should the following the tour guide, the tour guide must a have a control to make other player to come along with him. I saw this kind of features in some game like we walk with a NPC which tells us the game's story after that ends we gain the control again and we procced the game. Is it possible to make like this in unreal engine?
I am building this feature for a game where i show the places of a house or something like that to other person.
Please anyone if you have any ideas about that let me know.

Coming from maxwell render and having spent lots of time in Unreal now: We are now able to produce some very nice results, but it seems many of the settings (most) are still mysterious to us and there isn't a great source of understanding to dive deep into how everything inter-plays. In part, we expect to find that the complexity is what lends to unreal engine's ability to produce phenomenal imagery, but I'm just wondering what other people think about this?
Lastly, I would add that there are lots of tutorials out there that tell you to use a specific setting or workflow but don't really dive deep into the fundamentals of WHY to do things a specific way. e.g., "Use this number, it seems to work good for us". Maybe we just haven't found them.
mellow crater
I think the reason that you do not see "use this number" kinda things is because it is extremely individual and preference based. Of course there may be "values that mimic this exact light bulb IRL" - but that is so specific I don't think you will find it in any tutorials. This is where you as a studio need to do research to get "your look" to stand out. @golden token
golden token
@mellow crater thanks for the reply. I was kind of saying the opposite. That we see lots of tutorials where settings are recommended but no in-depth deep explanation into the “why” is given. I remember back in the day someone wrote a book that gave a super thorough explanation of each of the settings in Vray.
Like what does that setting actually do. We tend to find out by trial and error and making one change and then baking lighting to see what has changed if anything at all. It seems like a very slow way to approach this lack of info.
Some settings are definitely physics based but not everything is so self explanatory

Hi guys i need a urgent help, I am doing a House in the unreal engine as a first person game the problem is i am not getting the same lighting as in the viewport when i play the game.

pastel summit
Getting close to wrap this one up. my first time rendering with Luoshuang's GPU Lightmass, is there any way I can boost the quality? all cc welcome
wicked willow
@pastel summit great job!
pale prairie
that looks amazing, technically speaking the lighting quality looks to be as good as its going to get
composition and camera placement is amazing too
only critique is that the spherical light on the left side looks a bit out of place
the contrast is strong enough that I can see the numerous flat edges of the "sphere" against the background of the wall
I would recommend having a light source emitting light from inside a semi opaque sphere as opposed to simply having an emissive material applied to the sphere itself
sweet fossil
Agreed the light is a bit off but it also looks like you've got a light leak behind it going up the wall too
royal osprey
I would turn up the bloom, I like convolution bloom, but that's personal preference.

cheers guys, amazing feedback!
@sweet fossil i didn't notice that light leak thanks for pointing that out!

I was wondering what is the system specifications need to make a small game (with 2 villas and a 2 floor apartment with high quality photorealistic assets) as a third person game in unreal. I have 32gb ram 2400mhz, i5 9th gen 2.90ghz , 2gb graphic card is this enough?
I am asking this because the moment i import even one floor of the apartment the ram usage is at 9gb out of 32gb. Will it comsume more eventually?
spare gust
@tawdry iris Sounds like you're using a laptop designed for entry level workstation purposes, such as engineering/CAD or offline rendering.
Guessing it's an i5 9400 with a GTX MX150 2GB.
When developing for realtime applications you are almost certainly going to be GPU-bound, so the largest part of your build budget should be going towards the GPU.
For developing in Unreal you'd probably want a higher budget graphics card such as a GTX1070 - these should be fairly cheap second hand as we're nearing the RTX30 series.
For the question about RAM, unless the floor is extremely high in polycount, then 9GB sounds a bit high for an otherwise blank project. 32GB of RAM should be more than enough for any professional development, except for maybe processing photogrammetry wherein more RAM is always better.
tawdry iris
@spare gust thank you for your advice. I will upgrade my graphics card then.
spare gust
If your on a tight budget second-hand 10 series would probably be a good idea. If budget isn't an issue, then I'd wait a month because both Amd and Nvidia are releasing new cards very soon. 🙂

royal osprey
Well I personally don't recommend water cooling, it does allow lower temperatures but they are not as fail safe, and when they do fail it can be catastrophic. Get the best Noctua Air cooler you can find. I haven't used my DVD drive in YEARS so I'd skip that. 64gb of memory is a bit overkill unless you use AfterFX or substance, still future proof so it's all right. I'd change the 2080 super for a 2080TI the memory difference alone is worth it for Unreal arch viz.
And the power supply is a bit on the limit I'd go for a 850w at least.
If you don't want to spend so much up front just get the NVME drive, skip the other two, and add more later as you need them.
white sinew
nvidia 3000 series about to release totally w8 for that if possible

@mellow crater looks good. One recommendation consider a small form factor pc.. no more need for a laptop and easy to upgrade

@wicked willow - heres the updated build https://pcpartpicker.com/user/taholmes160/saved/#view=nDBcbv Not using a laptop - dont want one - - -- Im using a midtower -- I prefer big cases for this type of machine
@royal osprey Ya, I dropped the DVD Drive, Im going big on memory and I am using substance, as well as doing large models in blender -- I went with the 2070. the 2080 is too pricey for not a huge gain -- local renders will be test renders (small and lower res) final renders go to SheepIt
royal osprey
the 2080 is not just faster but it has more video memory. Will let you use bigger textures and bigger lightmaps.
mellow crater
@white sinew whats the advantage of the 3000 series? and whats the price point?
@royal osprey -- im looking here for a second
royal osprey
the 3000 series pricing is still rumors
white sinew
we will find out in 14 days
royal osprey
it has been rumored to be 20% faster (2080ti vrs 3080ti, if it's called that)
mellow crater
ok, I just compared the 2070 with the 2080 and its almost 400 more -- I really cant justify that much extra for what I'm doing
royal osprey
everything points to GPUs doing the heavy lifting in the future so a better GPU will make the most difference on a system by far. still you can upgrade later.
white sinew
yea 1500 for a 2080ti at this time seems a lil crazy tho
mellow crater
ya, and I'll probably do that -- if necessary -- I agree the GPU's are gonna be doing a lot of the work
yep
white sinew
i believe the announce or release is in 14 days
mellow crater
ya, ive heard rumors of that -- im willing to bet it will be 1700 to 2000USD -- I REALLY cant afford that
royal osprey
I am still sitting on a 2070 ti, but I'm saving, I need more video memory for large bakes in Unreal.
white sinew
like dann said it all speculation at this point
mellow crater
yep -- im on a GeForce 720 right now....
white sinew
but the announce will prolly drop the 2080 in price a bit
mellow crater
so ANYTHING is gonna be an upgrade
royal osprey
lol yeah
mellow crater
ya, i can see that happening
white sinew
720 is a bit rough yea
mellow crater
it works - I bought it b/c it allowed me to actually start blender -- and has 3 outputs -- but its faster to render on the CPU on a Core i3 than to use the gpu
white sinew
could get a 300% card and just see where it goes
royal osprey
wow.. you will notice a huge difference then
mellow crater
ya, im kinda excited to be honest -
white sinew
could just get what u want now and totally ignore all the new cards tho
royal osprey
a 2070 is probably 5 times faster than a core i3 with blender.
white sinew
like after the 3000 AMD is gunna release something aswell
white sinew
ahh thats a sick build
white sinew
depending on what u do i might drop the cpu a lil and go for more vid card, but wouldnt with the new gen comin out in 2 weeks
nvid pretty tight lipped about it

render and sculpt is something else tho, i hardly ever do a render
sculpt is single core
well whatever you do just enjoy ur rig 😄
I usually get a less high end rig but get em more often

I have a 10 year old machine that still hangs with todays hardware

guess i have a new rig that hangs with urs 😛

single threaded performance is crap, but otherwise it's pretty nice.
white sinew
like 600$ total new atm?
mellow crater
LOL - ya, dual xeon is tough
royal osprey
the new threadrippers are way faster, newer rizens are a little faster, took, them long enough.
mellow crater
ya -- the thread rippers are crazy expensive
white sinew
with that 400$ vid card the new release wont impact you that much even if they are really great tho
400$ mAX :p
mellow crater
ya -- we'll just have to see -- Im planning to purchase as soon as the money arrives
white sinew
if u go 1500$ 2080ti and they drop 500$ in 2 weeks its a dif story 😛
mellow crater
I'd be all growly
white sinew
just dont look at new hardware for a few years when u get it
royal osprey
they might, they might not, I think it really depends on AMD.. if they come out with a competitively priced "big navi"
mellow crater
yup
white sinew
lookin at console specs they wil make some decent card after nvid
royal osprey
the 2080ti lauched at $1200, 2 years later it's still t hat

yea its fecing bull if u ask me 😛

damn bastards want my $$

this 3000 series wil only compete with themselves on release

https://opendata.blender.org/ This chart is pretty interesting, most GPUs are faster then CPUs in blender, except the really high end Threadrippers.
white sinew
GPU also use a lot more power usually
dunno what blender render farms use gpu or cpu
hell i dont even know if they generate the same image 😄
mellow crater
Sheepit prefers cpu b/c of stability issues, but can use both -- generally the images will be identical

You can find a Windows Pro license a lot cheaper than $110
The RAM could be a bit better for a Ryzen 3950X. Look for 3600mhz @ Cl16 timings 16-18-18-36 if you want optimal boost clock/overclock performance
$80 being spent on RGB fans that could probably be used towards something else?
RTX 30 or 21 series is likely coming out by October. Would advise against buying an RTX 2070, particularly when the super versions are usually better price/performance
3TB worth of 2.5" SATA SSDs... Could consider dropping them (lose 1GB) and switching to a PCIE 4.0 m.2. nvme SSD 2TB. Archive inactive projects on HDD - it's unlikely you have more than 2TB worth of active assets
b550 is fine for a single pcie 4.0 ssd, but consider x570 if you might want a second as b550 only has one pcie 4.0 for m.2., the rest are 3.0
Phantek's case uses a lot of plastic doesn't it? For $50 more you could look at NZXT H510, H510 elite, H510i which are fully metal, and have a front usb c port (check your b550 motherboard has a usb c header)
850w PSU might be overkill when your estimate wattage is 503

hello, can someone help me with this, how can i set this type of UV to parametter, it wont let me, i tried put 2 constant into append node to replace but it not the same
it doesnt work when i tried this

Hey all, just finished up this project of mine. I dedicated this project to learn more about gpu lightmass and lighting.
Trailer: https://www.youtube.com/watch?v=mcpLixHOfis&feature=emb_title
Full project details: https://www.artstation.com/artwork/Po61E1
spare gust
@pastel summit Would be interested to see a Lighting-Only mode comparison between CPU and GPU Lightmass bakes, personally I use SwarmAgent so the bake times aren't a big deal but if the GPU can address things such as seams between flat surfaces without the need to perfect UVs that would be neat
royal osprey
@spare gust you still need decent UVs, That said when you have two modular pieces fit toghether they tend to have differences in lighting using regular lightmass, those differences are elimitated using GPU lightmass. It's not perfect, I struggle with fringe case emissive materials, since they tend to be noisy if they are too small/bright. In general GPU lightmass is way faster and looks better.
spare gust
Seems are produced between modular pieces on CPU lightmass iirc because the two modular pieces are rendered on separate threads of the cpu
So wondered if the same was still an issue on GPU
On CPU you have to hide the seem or get the UVs grid snapped properly, and the lightmap resolution correct, with a high enough quality of rendering
spare gust
For ArchVis not a problem because performance isn't as big of a deal, but with realtime games/experiences it can be an issue
If GPU was officially supported and could beat SwarmAgent CPU then it would be a no brainer
Have Epic suggested anywhere that they'll officially integrate it? I kind of assumed that with Lumen coming mid next year that they might just leave it
royal osprey
GPU is being worked on, you can test it out if you dowload the beta
the implementation is really cool
spare gust
Guessing you have to pull a custom build from GitHub?
royal osprey
https://www.youtube.com/watch?v=uXYNAtux_94&t=1029s this was 4 months ago, so it should be even better now.
not sure about installation

does anyone know why when i build my lighting in a level my model does this?

Can you show us your lightmap UVs?

@short plaza Take two screenshots in the viewport:
One of Lightmap Resolution View (Alt+0)
One of Lighting only mode (Alt+6 I think)

i want to make a light ablle to be turned off on cinematic for video purposes. How can i do it? I want to be able to move like a chair around without it losing its lighting as well...

anyone know how to fix this curtain error lighting ? the one on the right doesnt have direct sunlight , the one on the left has a small sunlight go throught it and whole lightmap just go crazy. i checked UV, material and it looks fine, i dont know which button on light setting should i turn off
@boreal meadow there area few nice tutorial video that you can use

question for profs, maybe someone here has experience with this: My client is paying me roughly 40$ per hour for a video render fly around of an interior Im creating. If they wanted the 3D model of the building for whatever reason, how much extra should I charge?

good morning, i need help, i made a curtain animation in max and exported in alembic, when importing in unreal i cannot control the mesh and when using translucent material for the curtain, even in dark areas the mesh is not dark , how to solve this problem?
solemn hawk
What do you mean you can’t control the mesh?
cosmic nebula
@rare badge need more deets bra
rare badge
ok, what else can i provide
@solemn hawk for example when I click on plays the animation is all atrophied, not because of the material or the mesh
solemn hawk
That seems like an issue with the mesh you imported rather than unreal
Your material isn’t going to affect how the mesh animates
cosmic nebula
can you post a video / gif
rare badge
@solemn hawk ok, i realized, now my problem is trying to export 3ds max animation correctly and import it into unreal. in version 4.25 when I import an Alembic file, it doesn't have a movable option, which I think can correct flaws.
rare badge
@cosmic nebula I'm very new at this, I could specify what information you want, please

Hey guys, I want to make some rattan furniture, like this
https://www.turbosquid.com/3d-models/visualization-furniture-rattan-bamboo-3d-model-1524860
However, it'll be an asset for a game. Granted, there will be not much other than the house and interior stuff, so what's the best way to go about modelling it? Modelling everything in such woodwork would mean this could easily get to at least 20k polies. What's the best way to balance the realism with performance?
the one in the link is a bit simpler, the one I want to make is at least twice as complex. Sofas (sitting and for back and arms) will cover quite a bit of it, but the areas around will be exposed.
hardy shore
hi guys, does anybody know how one would setup the texture so that object meshes would have a random coordinate offset and contrast, or what shoud I look for even?
wicked willow
I'm getting these hard shadow edges at the end of my reflection spheres..is this normal or is there some setting I'm missing ?
royal osprey
@wicked willow it's normal, you need to have at least one big reflection sphere covering everything.
sharp iron
Not sure if this is the right place to ask...
Anyone know what this phenomenon, where shadow edges become "warped", is called?
I increased a light source's Shadow Filter Sharpen param, in hopes of getting a clean edge on shadows. Instead I get this.
tidal prairie
Greetings. Any way to remove those glitches in area of 100% shadow?
As this does nothing:
hallow arrow
@tidal prairie that is due to backface detection I added in 4.24
whenever you see such artifacts try to find if there's a back face in front of them
and mark the back face material as two sided
tidal prairie
There is...waterfall is a single plane
but that will unnecessary increase cost of material
hallow arrow
🤔 to me the increased cost of double sided material sounds like a myth
tidal prairie
@hallow arrow ok...it definitely more expensive for translucent ones, but i was not sure about masked
Thank you for reply!
lavish bramble
Hey everyone! I am trying to port this archviz project into the Oculus Quest and I am having trouble with the lightmaps (created with Luoshuang’s GPU lightmass).
Has anyone have had any luck with Lightmaps on mobile? I am trying to use the HQ_Lightmaps on the Oculus Quest but it doesn’t seems possible without enabling Mobile HDR
I know that this must be possible since the game “Red Matter” has some stunning visuals on the Quest and I don’t thing they could have achieve this with the normal LQ_Lightmaps
hallow arrow
maybe @shadow fern has some answer for you
lavish bramble
Didnt realize we had one of the developers right here!
Thank you @hallow arrow I am going to try to get in contact with him
shadow fern
HQ_Lightmaps are totally possible, just need to turn on directional lightmaps on the material settings. Mobile HDR is totally not required!
tribal gyro
I have a lighting question
If I turned eye adaption off and set Min and Max exposure to 1 and my scene is very bright, does that mean the lights are just too bright? and how can I make it look darker without adjusting all the lights and re-baking? If eye adaption is on everything is fine, but I don't want it
royal osprey
you can set min and max to another number, keep them the same. both at .5 will be brighter, both at 1.5 will be darker.
or play with "exposure compensation" or... there are many ways.
sharp vessel
where might I ask for advise on learning for unreal? I got the possibility to get a paid course by my company, and I want to find out what could be my best choice

@sharp vessel check out unreal academy, it’s a free resource from epic, tons of videos geared towards beginners

Hey guys, has anyone used VRay TriPlanar Texture instead of the usual UV unwrapping? If so, can it be used for game dev instead of the traditional unwrapping or does it only work inside 3ds max?
